Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. One of the three ossicles in the middle ear; also called the stirrup - it is attached to the oval window of the cochlea and is the innermost of the three ossicles.






2. A bone of the sternum.






3. The joint movement that decreases the angle between two bones.






4. The shoulder blade; the most proximal bone of the thoracic limb. No bony connection exists between the scapula and the axial skeleton.






5. The cartilaginous joint (amphiarthrosis) that unites the two sides of the mandible at the rostral end in dogs - cats - and cattle.






6. The bones along the central axis of the body; made up of the skull - hyoid bone - the spinal column - the ribs - and the sternum.






7. An immovable joint; also known as a synarthrosis. The bones are firmly united by fibrous tissue; includes the sutures between the skull bones.






8. The bones of the neck portion of the spinal column.






9. The hind limb.






10. A flat articular surface - such as between carpal bones and between the radius and ulna.






11. Another name for cancellous bone.






12. A hole in the bone.






13. The midline barrier that separates the left and right nasal passages.






14. The bones of the limbs (appendages)






15. Skull bones that are external bones of the face; form a portion of the orbit of the ey and the rostral portion of the zygomatic arch.






16. Heavy - dense bone made up of tiny - tightly compacted - laminated cylinders of bone called haversian systems; makes up the shafts (diaphysis) of long bones and the outer surfaces of all bones.






17. Skull bones; external bones of the cranium. These bones make up the 'forehead' region of the skull and contain the large frontal sinuses. The cornual process in horned animals is an extenion of this bone.






18. One of two concave - half moon - shaped - cartilaginous structures on the proximal surface of the tibia that help support the condyles of the femur.






19. The joint movement that increases the angle between the two bones.






20. The vestigial metacarpal and metatarsal bones of a horse's leg. There are two spint bones in each leg: one on either side of the cannon bone (MC/MT III). The medial bone is MC/MT II and the lateral bone is MC/MT IV.






21. The hormone secreted by the thyroid gland that prevents the level of caclium in the blood from getting too high.






22. The visceral bone in the penis of dogs that partially surrounds the penile portion of the urethra.






23. The joint between the femur and the tibia; called the knee joint in humans.






24. A beak - shaped process at the proximal end of the trochlear notch of the ulna; when it fails to unite with the ulna - an ununited process can cause the elbow joint to become unstable - leading to lameness.






25. The junction between two bones; can be completely immovable (fibrous) - slightly movable (cartilaginous) or freely movable (synovial).






26. One of two bones (the radius is the other) that form the antebrachium - or forearm; forms a major portion of the elbow joint with the distal end of the humerus.






27. A large - rounded articular (joint) surface; examples are found on the distal ends of the humerus and femur.






28. Membrane bone formation; the type of bone formation that occurs only in certain skull bones when bone froms in the fibrous tissue membranes that cover the brain of the developing fetus.






29. The single - dorsally projecting process of a vertebra.






30. The second cervical vertebra; it forms the atlantoaxial joint with the first cervical vertebra - the atlas.






31. A toe that does not reach the ground - such as the first digit of dogs and cats and the rudimentary medial and lateral toes of cattle.






32. The bones of the skull that surround the brain. External bones: the occipital bone - the interparietal bones - the parietal bones - the temporal bones - and the frontal bones. Internal bones: the sphenoid bone and the ethmoid bone.






33. Bones that are longer than they are wide; most of the limb bones are in this category.






34. The hematopoietic type of bone marrow.






35. Bony arches below and behind the eyes of common domestic animals; in dogs and cats they form the widest part of the skull. Made up of the rostral - facing zygomatic process of the temporal bone joined with the caudal - facing temporal process of the






36. A freely moveable joint; also known as a diarthrosis.






37. The process on the distal end of the distal phalanx of dogs and cats that is surrounded by the claw in the living animal.






38. The joint movement whereby an extremity is moved away from the median plane.






39. The last - most caudal sternebra; the _____ process.






40. Long bones of the axial skeleton that form the lateral walls of the thorax; dorsal portions are made of bone and form synovial joints with the thoracic vertebrae. Ventral portions are cartilage.






41. Skull bones that are part of the external bones of the face; form the bridge of the nose or the dorsal part of the nasal cavity.






42. The most caudal rib or two in the rib cage; a rib whose costal cartilage does not unite with anything but rather ends in the muscle of the thoracic wall.






43. The most caudal of the three pairs of bones that make up the pelvis.






44. A depressed or sunken area on the surface of a bone; usually occupied by muscles or tendons.






45. The bony roof of the mouth; the division between the mouth and the nasal cavity. Made up of portions of the maxillary and palatine bones.






46. The outer layer of a bone that is composed of compact bone.






47. A skull bone; an internal bone of the cranium. This single bone is located just rostral to the sphenoid bone and contains the cribriform plate.






48. A ball - and - socket joint - such as the shoulder or hip joint. Capable of all synovial joint motions.






49. The front limb.






50. The process of a vertebra that forms a synovial joint with an adjacent vertebra.
